The BLOBs alias the Breath of (Galaxies) Death: Enigmatic Diffuse Ionized Gas Structures in a Cluster of Galaxies near Cosmic Noon

Our paper by C. Maier et al.  with the title: Enigmatic diffuse ionized gas     structures in a cluster of galaxies near cosmic noon has been published in the Astronomy & Astrophysics journal.

The BLOBs represent the Breath of Death of Dying Galaxies:  They are tracing the quenching of star formation in galaxies in the center of the cluster at a redshift close to cosmic noon, z ~ 1.5.  The central area of the cluster contains only passive galaxies and an AGN.

Lecture Physical Properties of Galaxies (Master course)

 

In Winter Semester 2024/2025 I will give a lecture on the Physical Properties of Galaxies (Master course) together with Prof. Ziegler.

Aims, contents and method of the lecture course on the Physical Properties of Galaxies are:  Students will gain a detailed insight into the galaxy realm from a phenomenological perspective and learn various methods for measuring the physical properties of galaxies.

Contents include: Luminosity/mass distributions of stars, gas, and dust; stellar and gas kinematics; stellar and gas abundances; star formation history; chemical enrichment; galaxy scaling relations. Various analysis methods and tools for measuring these properties of galaxies using multi-wavelength observations will be discussed.

Assessment and permitted materials: There will be 1 written exam at end of semester and participants need to present a paper in the exercises. During exam no electronic or AI tools are allowed.
